Bridging the industry divide between the technical expertise of engineers and the aims of market and business planners, Making Telecoms Work provides a basis for more effective interdisciplinary analysis of technology, engineering, market and business investment risk and opportunity. Since fixed and mobile broadband has become a dominant deliverable, multiple areas of transition and transformation have occurred; the book places these changes in the context of the political, social and economic dynamics of the global telecommunications industry. Drawing on 25 years of participative experience in the mobile phone and telecommunications industry, the author closely analyses the materials, components and devices that have had a transformative impact. By presenting detailed case studies of materials innovation, such as those shown at success story Apple, the book shows how the collaboration of technological imagination with business knowledge will shape the industry’s future. Makes a link between the technical aspects and the business practice of the telecoms industry, highlighting the commercial and economic significance of new developmentsGives a historical analysis of past successes and failures in order to identify future competitive advantage opportunitiesSupplies detailed case studies of supply chain disconnects and the impact these have on industry risk and profitabilityBrings together technological detail with analysis of what is and is not commercially important, from the implications of energy and environmental networks to the technical details of wireless network hardware.

5G and Satellite RF and Optical Integration, the latest ‘hot off the shelf’ groundbreaking book from Artech House authored by subject specialist Geoff Varrall is packed with essential time critical information. This updated edition has everything needed to know in order to understand the new world of terrestrial and non-terrestrial telecom technology. It analyzes the radio spectrum/band and technical specifications under consideration for 5G, along with the related performance, cost, and vertical market expectations. In addition, the book studies the cost of coexistence between 5G operators and other user communities' co-sharing spectrum, including GNSS; radio astronomers; radar; GSO, MEO, and LEO satellites in the Ku, K, and Ka bands and above; and satellite TV. Also covered is the role of free-space optical technology in 5G and satellite networks and what interference issues will arise from new band allocations. This includes co-shared allocations and how interference will be mitigated in and between next generation terrestrial and satellite 5G networks. The publication coincides with an inflection point where terrestrial, nonterrestrial, and RF and optical networks could be integrated in a financially useful way.

This title is written as a direct follow on to Varrall's 2016 book. It provides an update on 3GPP Release 16 and 17 and the related `New Radio' physical layer specifications. It also studies the implications for World Radio Congress 2019 and related 5G and satellite standards work and discusses the likely impact on the future enterprise value of satellite and 5G operators and their associated supply chains. The satellite industry is entering a golden age of innovation which is having a profound impact on the delivery economics of connectivity from space. Over the past two years there has been a remarkable technical and commercial transformation in the satellite industry, with new service models emerging both from existing established geostationary orbit (GSO) operators to 'NEWLEO' operators such as LEOSAT. Many 5G vertical market use cases could potentially now be served more efficiently from space, but several regulatory and competitive positioning issues need to be resolved before these techniques can be deployed and trusted universally. This book documents these techniques and the associated interference modelling and explores the evolving business and financial and commercial implications of this transformation process. It also captures the emerging focus on discrete vertical markets and their specific physical layer and upper layer protocol and performance requirements.

A fascinating story of telecommunications in Cornwall from 1830 through to the present day, spanning the earliest days of the terrestrial telegraph network, the laying of subsea cables from 1850 onwards, high power long distance radio from 1900 and satellite communication from the early 1960s. We start at the Geevor tin mine in Pendeen then head down the coast to Land’s End, the most westerly point of the English mainland (the shortest route to New York). From Land’s End we come first to Porthcurno where the first subsea cable to India came ashore on 8th June 1870, then via Newlyn, Penzance, Marazion and Porthleven to Poldhu Cove near Mullion from where (30 years later on 12 December 1901) Ambrose Fleming summoned sufficient radio energy to send the Morse code letter S (three dots, no dashes) to Marconi in Newfoundland. From Poldhu we head a few miles inland to Goonhilly where on the 11th July 1962 (another sixty years on), TV signals from the newly built satellite communications antenna, Arthur, were transmitted and received via a beach ball sized satellite called Telstar. Fast forward another sixty years (2022 onwards) and those legacy dishes support NASA and ESA space missions. There is also a state of the art data centre and a Low Earth Orbit ground station. The Telecoms Coast is not written as a guide book but if you were minded to head down the coast from Pendeen with a compass and a smart phone you could be relaxing a mere 100,000 steps later with a well-earned gin and tonic in the bar of the Housel Bay Hotel. There you can reflect that with the benefits of a time machine you could have crossed paths with John Pender in 1870 in Porthcurno as he planned the next long distance subsea cable to arrive on the sandy beach. Fast forward thirty years to 1900 and you could have been chatting to Mr Marconi and Major Flood Page as they planned the new generation of high power long distance radio stations along the Cornish Coast. A quick teleport to the present day and you could find a bevy of satellite engineers from Goonhilly enjoying a beer or three in the hotel bar while discussing radio networks on the Moon or how to talk to Mars.
